Noto CJK Variable Fonts


Switch the default Noto CJK fonts for Chinese, Japanese and Korean from static to variable fonts.


Current status

Detailed Description

In order to reduce the font size in Noto CJK fonts, we plan to switch to use the variable fonts by default.

  1. Split the google-noto-cjk-fonts package into google-noto-sans-cjk-fonts and google-noto-serif-cjk-fonts, and provide the variable fonts in google-noto-sans-cjk-vf-fonts and google-noto-serif-cjk-vf-fonts.
  2. Drop several sub packages which are not installed by default from the google-noto-cjk-fonts package.
    1. Like google-noto-sans-cjk-*-fonts, google-noto-sans-*-fonts, google-noto-sans-mono-cjk-*-fonts, google-noto-serif-cjk-*-fonts and google-noto-serif-*-fonts
  3. Install the Noto CJK Variable Fonts by default.

Fedora Copr for testing:


Benefit to Fedora
